Abstract: 4299. Johnson, J. Y., [Enterprise Mannfacturing Co.]. March 6. Sharpening.-Relates to devices for the knives of food-cutting machines, such as are used for cutting or slicing meat, bread, fodder, and the like, the devices being formed in combination with the machines. Fig. 2 shows in section a rotary food cutter or slicer with the sharpener E o u t of engagement with the cutting-blade b<1>. The sharpener E, consisting of a steel rod having a ribbed or otherwise roughened surface.is carried from the end of an arm D in such a way that it may be moved in or out of contact with the bevelled edge of the cutting-blade. By means of a screw e', the steel may be turned so as to present fresh surfaces. The sharpener is held from the blade by a latch g, which, when thrown back, releases a spring which brings the sharpener into contact. Within the recess a in the machine the buffer a<2> is placed, so that, when the blade passes the steel, the latter will strike the buffer and be held in the path of the blade as the blade rotates. When applied to a food-cutter having a vibrating blade, the blade is pivoted to the frame and the position of the sharpener is reversed.

Title: Improvements in the Manufacture of Rotary Cutters for Milling Machines and the like.
Inventor: JANSEN BRUNO
Filed: 1901-06-06
Granted: 1902-05-08
Abstract: 11,616. Jansen, B. June 6. Milling; tools.-Relates to the production of milling and other rotary cutters by casting them in the desired shape from a prepared steel. A mixture of cast iron, cast steel, and wrought iron, or of wrought and cast iron, or of cast steel only, containing the percentage of carbon the tool is to have, is melted, and an excess of carbon is added to render it more fusible, by adding cast iron with a large amount of carbon. The mass is then stirred or puddled to remove the excess of carbon. When it becomes slightly viscous, it is highly heated, and aluminium added to prevent the formation of gases, after which the mass is poured into heated and dried cutter moulds and allowed to cool. The resultant steel has the carbon uniformly distributed, and can be hardened. A suitable mixture is 24 parts by weight of a mixture representing the percentage of carbon the tool is to contain and 11 parts of grey pig iron containing 3¢ per cent. of carbon.

Title: Improvements in Electric Fuse Boxes.
Filed: 1901-11-19
Granted: 1901-12-21
Abstract: 23,376. British Thomson-Houston Co., [Aller, T. van]. Nov. 19. Cut-outs.-The box is so arranged that the pressure and heat of the gases break the fuse, and metal is not scattered outside the box. In the form shown in Fig. 1, the box is formed in three parts clamped together by a bolt 6. The upper part, Fig. 2, is recessed at 8, 9 to receive the fuse clips. The fuse 13, Fig. 4, is supported on a fireproof asbestos sheet 14, the central portion entering the channel or groove 12, the ends 12<a>, 12<b> of which form chambers over discharge openings 13<a> in the second member of the box. The gases pass out through channels 17 connected to vents 19, 19<a>. The channels 17 are filled with a granular cooling-material, and the vents are fitted with a pivoted cover, which is blown over and indicates when a fuse has melted. The hot gases formed when the central portion of the fuse melts circulate around the strips 15, 15<a> over the openings 13<a>, and cause these to be blown out. Fig. 7 shows a modified form of box, having tortuous channels formed therein. The fuse is led across a diaphragm 30, 30<a>, the central part being in an air chamber. The tortuous channel crosses the path of the fuse at several points, such as 33, 33<a>, thus interrupting the fuse at two or more points, and extinguishing the arc.

Title: Improvements in, and in Apparatus for, the Manufacture of Chlorine and other Chemical Products.
Inventor: DIEFFENBACH OTTO
Filed: 1901-12-28
Granted: 1902-12-24
Abstract: 26,537. Dieffenbach, O. Dec. 28. Chlorine.-When two gases are required to be passed in a heated condition over a catalytic substance, the mixture generally attacks the apparatus in which it is heated. Of the two gases, however, one is usually inactive. The first part of this invention consists in heating this inactive ingredient only (for example, air in the Deacon process of making chlorine). It is heated to a temperature higher than the mixture is required to be, and is then mixed with the other gas. The second part of the invention consists in carrying on the process so that the region of highest temperature in the catalytic apparatus shall continually travel in a closed cycle. For example, in the apparatus shown, there are two charged catalytic chambers I, II, and an arrangement of tubes and valves. Suppose the valves e, a, d to be open, and b, c, f closed. The heated gases then pass first to I, then to II, and then escape. As the process proceeds, the catalytic substance, for example, copper chloride, will partially volatilize from the hottest and most energetic part of the apparatus, that is, the chamber I, to the chamber II. When this occurs, the valves e, a, d are closed, and f, b, c are opened, whereby the gases pass first to II, then to I, and then escape. The place where now there is most catalytic material, that is the chamber II, is also the hottest and most energetic. As the process goes on, the catalytic material is carried back to I, and the valves are therefore again set as at the beginning. Any other arrangement of apparatus suitable for carrying out the process may be used.

Title: Improvements in Acetylene Generating Apparatus
Inventor: DOMAN WILLIAM
Filed: 1902-09-29
Granted: 1903-08-27
Abstract: 21,133. Doman, W., and Streeten, B, S. Sept. 29. Acetylene.-In an acetylene generator in which the water is allowed to drip from a separate reservoir on to the calcium carbide, the water tank B, Fig. 1, is fitted with a long vertical tube C, which is provided with a gas outlet E and is connected by a flexible pipe D to the top of the gas bell. The lower end of the tube C acts as a condensing - chamber for the moisture in the acetylene, and may bo fitted with a tap. The water reservoir F is supported from the tube C, and is connected by a second flexible pipe to the top of the bell. When a number of carbide holders I or I', Figs. 1 and 2, are employed, they are arranged one above the other in a casing L or L<1>, within the bell, or under the reservoir F<1> when no bell is provided. When water accumulates in one of the upper holders I, I', it escapes through a hole in a drip pipe M to the next lower holder. These holes are at such a height above the bottom of the holders that the water escapes before all the carbide in the holder has been acted upon, so that there is no slackening of the action from the water having to percolate through a thick layer of lime residue. The drip pipes M are surrounded by pipes N which prevent the residue from choking the overflow holes but allow water to pass to the carbide. Separate overflow compartments, fitted with wicks which hang down into the lower holder, may be used in place of the pipes M, N.

Title: Improvements in Electrical Signalling Apparatus for Transmitting Orders or Signals from one Remote Point to another.
Inventor: HAUSS ALBERT FREDERICK
Filed: 1902-10-14
Granted: 1903-02-05
Abstract: 22,336. Hauss, A. F. Oct. 14. Signals, electric, indicator or visible, and reply or tell-tale.- Relates to electric apparatus applicable for signalling from the bridge, pilot-house, or conning-tower of a ship to the engine-room, and vice versÔ. Each instrument comprises a transmitter and receiver, and a number of instruments may be connected in the same system. The transmitting-handle H<1>, H is fixed to the sleeve h mounted on the spindle c, and is provided with a pointer h<1>, which works over the transparent dial b<1> bearing the orders &c. The pointer o<1> of the receiver is mounted on the spindle o, between the dial and the translucent plate Q illuminated by the electric lamps S. The spindle o is moved by the armature 0, which is mounted between the poles n of the actuating-coils n<1> of the receiver. The coils n<1> are connected diametrically in pairs, as shown in Fig. 4, and each pair is connected by a wire v<1>, w<1>, x<1> to the corresponding pairs of crossconnected contacts d<1> of the transmitter at the distant station. With this arrangement, each circuit serves for two different signals, such as "Slow-Ahead," and "Full-Astern." The central contact d' is single, and is connected by the wire y<1> to the pair of coils n corresponding with the central or "Stop" position. The transmitting- lever H has an arm J provided with a bridgepiece which serves to connect the pairs of contacts d' separately to the segmental battery contact d, the movement of the transmitter thus energizing the pairs of coils n<1> in corresponding order, and causing a corresponding movement in the receiver. To avoid waste of battery power, the battery circuit is normally open between the contacts e, e', and is closed only when the contact j is moving from one contact d' on to the next, the closure being effected by the contact f<1>, Fig. 2, on the lever F actuated by the cam-disc M. The contact f<1> also closes the signal-bell circuit. The lamps S are cross-connected in pairs, and the two pairs are connected in parallel to the battery, so that, in case of failure of one pair, a uniform illumination of the dial will still be obtained from the other pair. A switch s is provided in the lamp circuit. The spindle o is provided with a toothed disc o<2> engaged by spring-controlled rollers p', which control and limit the movement of the pointer o<1> from centre to centre of the successive indications. The transmitter is similarly controlled, by a roller on the spring-controlled lever G engaging the toothed disc L.

Title: Improvements in and connected with Electric Brakes for Railway and Tramway Vehicles
Filed: 1902-11-04
Granted: 1903-04-02
Abstract: 24,100. Lake, H. H., [General Electric Co.]. Nov. 4. Electric locomotives and motor vehicles.-Relates to electric and magnetic brakes for electric tramcars. Any brake shoe, on tending to stick, is momentarily demagnetized, and at once releases the revolving disc with which it co-operates. Fig. 2 shows the preferred arrangement. The equalizing-wire E connects the leads of the armatures A<1>, A<2> of the electric motors, which are assumed to be acting as generators and supplying current to the brake blocks B', B<2>. Should the speed of the armature A' fall below that of the armature A<2>, the current in the solenoid C<3> is decreased, and the arm D cuts in the entire resistance R<1> in shunt circuit around the shoe B<1>. If the armature continues to be retarded, or stops, part or the whole of the resistance is cut out. As the armature A<1> increases in speed, the arm D passes over the resistance contacts and finally opens the circuit and allows the entire current to pass through the shoe B<1>. In a modification, electromagnets, wound as shown in Fig. 1, control the arm D adapted to engage the contacts d<1> or d<2>.
